AI 25.4.1 GPU performance still very slow, cannot easily editing previous version files
Since AI 25.2 I've had problems editing files. With GPU features enabled, all UI functions, selecting, deselecting, all mouse dragging functions, menu selections are all extremely slow to respond, I'm talking several seconds between responses to clicks and movement. Turning off "Real Time Editing" helps somewhat, delays are shortened, but still very difficult to work with. Disabling Animated-zoom has no effect. Disabling GPU entirely, improves selection and dragging, but there is still a delay of several seconds after releasing the mouse button. This behavior seems restricted to editing files prior to v25.2, but not all. Preforming a "SaveAs" over the existing file does not solve the problem. I found copying and pasting the entire contents into a new blank document does seem to solve the problem, as the UI response is speedy in the new document, in the same session of AI ! New documents work normally. Copy and pasting is not a practical solution. I do not see any shape or color problems. I've refreshed AI 25 preferences, to no effect. I'm using AI 24.3 where these same problem files edit normally with GPU enabled!? I attached a typical example file. As of 9-21-2021 all my CC-Apps and graphic drivers are up to date. Video card is NVIDIA P5000-16GB/driver-v472.1/30.1.14.7212, computer HP-Z8 Xeon4112, Win21H1-19043.1237, MS HID mouse driver.

You can still use the Grid guides if you changes the Style to Lines under Preferences - Guides and Grid and then play around with colour and subdivisions to suit.

Oh ok, Illustrator's Grid. Yes, hiding the AI Grid (Win Ctrl+') made the problem go away! Thanks for the tip I never would have thought of that. I've always used the grid as a tool to "eye ball" the size of objects. It seems odd that such a simple function would cripple the graphic system the way it does. I can probably work without the grid most of the time. But I have a library of electronic symbols designed on a grid spacing of 0.025in, which works best for our publishing needs. Smart Guides does not always work well for placing the symbols, Grid Snap is a quick and accurate method to align the symbols and "wires". So, I hope this problem with Grid View can be resolved soon. Thanks again.

Thank you Egor & Simon, I tried turning off the grid layer and yes it did speed things up somewhat, I still have a significant delay when I try to click and drag an object. This level of response remained after I turned the grid layer back on. I saved the file to a new name, no change in performance. I then deleted the empty layers and unused objects, saved-as and restarted AI25.4 The slowness and stalling returned on opening the new file. I turned off icons for all but top layers in the layers pallette, no change. I opened another drawing with the same problem and that brought AI to a virtual stop, I waited 30 seconds to switch between windows.
If I switch to CPU preview the response improves, but there are still delays in the programs responses. I've also realized that most of the problem files were created from .AIT template files. The sample file was created from a template file last edited with AI24. The program behavior seems inconsistent to me. Other than the GPU/CPU switch I can't see any patterns that offer clues to the problem. -

If you hide the Grid on your attached file it seems to then work fine. Should be able to use the grid though.

I can confirm that! The file attached performs extremely laggy.
